Dolby Pro Logic II

Dolby Pro Logic II is an improved technique used to decode vast numbers of existing Dolby Surround sources. This technology enables a discrete 5-channel playback with 2 front left and right channels, 1 center channel, and 2 surround left and right channels instead of only 1 surround channel for conventional Pro Logic technology. There are three modes available: “Music mode” for music sources, “Movie mode” for movie sources and “Game mode” for game sources.

DTS Digital Surround™

DTS Digital Surround™ was developed to replace the analog soundtracks of movies with a multichannel digital sound track. This system produces practically distortion-free 6-channel sound (front left and right, center, surround left and right and subwoofer low frequency effect channels for a total of 5.1-channels).

DVD-AUDIO

DVD-Audio is an extension of the highly popular DVD format, distinguished by its capability to deliver high quality multi-channel audio capability previously unavailable in traditional packaged audio media.

Super Audio CD

DVD players that support Super Audio CD use a technology called Direct Stream Digital (DSD) to convert music into a digital signal that can be stored on a disc. Compared to the traditional PCM method (the technology used for CD), DSD offers a much higher resolution by following more closely the original waveform of music. With a frequency response of over 100 kHz and a dynamic range over 120 dB across the audible frequency range – some 64 times higher resolution than CD - Super Audio CD offers music reproduction that reveals details you just can’t hear on a normal CD.
